Too close to call
No published verdict for this pair: signal difference under 15 percent. These records clear the shared-dimension gate, but their relative signal-index gap stays below the verdict threshold.
Read the verdict ruleA comparison requires at least two shared usable evidence dimensions. For eligible pairs, the verdict applies a 15 percent threshold to the relative gap between the two complaint-signal indexes. It is not a mechanical failure rate or a complete reliability measure. Metrics below a sample gate show no value rather than an estimate.
Component groups · share of each record
Where each file concentrates
Bars use a 0 to 50 percent share scale. Shares are of each record's own classified reports, so the smaller file's percentages sit on fewer reports. A zero bar means the group does not appear in that record's published distribution.
